HIGH EFFICIENCY DUST COLLECTOR OF HEAT RECOVERY BOILER IRON OXIDES

摘要

A dust collector comprises: a driven axis arranged at one side of the opened upper end of an exhaust path; a driving axis arranged at the other side of the opened upper end of the exhaust path and facing the driven axis; a filter which is a filter for opening and closing the opened upper end of the exhaust path, has the shape of a roll wound around the driven axis, covers the opened upper end of the exhaust path by being spread from the driven axis toward the driving axis, and has an end at one side thereof connected to the driving axis; a driving motor connected to the driving axis to transfer the filter from the driven axis toward the driving axis by rotating the driving axis; and a control part connected to the driving motor to control the rotational rate of the driving motor. The filter includes a porous filter member; and an adhesive part placed on either or both surfaces in the porous filter member. Using the dust collector of a heat recovery boiler according to the present invention, a process for collecting and filtering particles in exhaust gas discharged from the exhaust path of the heat recovery boiler can be operated effectively. And low pressure loss and high efficiency can be maintained not to affect the operation of existing power generation facilities, and the high flow speed of exhaust gas can be maintained. Therefore, the dust collector of a heat recovery boiler according to the present invention can be installed easily on the exhaust path of the heat recovery boiler and can reduce investment costs about installation greatly.
